Patent number: 7771672Abstract: A variety of reactors that are arranged to treat aerosol particulates that are carried in a fluid stream passing through the reactor is described. In one aspect, the reactor includes a plasma chamber arranged to receive the fluid stream and subject particulates carried in the fluid stream to a cold plasma that has a sufficiently high concentration of reactive species to treat at least some of the particulates passing therethrough. A catalyst is provided downstream of the plasma chamber. The catalyst is arranged to enhance the conversion of reactive species that are contained in the fluid stream before the stream emerges from the reactor. In another aspect, a catalyst electrode is described. The catalyst electrode may include a catalyst material carried on an electrode. A potential may be applied to the electrode during use to attract charged species towards the catalyst.Type: GrantFiled: April 18, 2006Date of Patent: August 10, 2010Assignee: Airinspace B.V.Inventors: Vance Bergeron, Laurent Adrien Fullana

Patent number: 7452410Abstract: In various aspects of the invention, electrostatic filters having insulated electrodes are described. In such embodiments, care is taken to prevent the accumulation of opposing charges on the insulation, which, over time, would serve to significantly degrade the strength of the electrostatic field created in the dielectric, and thus reduce the performance of the electrostatic filter. A variety of mechanisms are described for mitigating the opposing charge buildup problem.Type: GrantFiled: April 18, 2006Date of Patent: November 18, 2008Assignee: Airinspace B.V.Inventors: Vance Bergeron, Laurent Adrien Fullana

Publication number: 20080170971Abstract: An air purification reactor is described that has a variety of improvements. In one aspect, the air purification reactor includes an ionizer (or plasma chamber), an electrostatic filter, a photocatalyst, and a UV light source that is distinct from the ionizer. The ionizer is arranged to introduce ions into a gaseous fluid stream passing through the air purification device. The electrostatic filter is located downstream of the ionizer and is arranged to electrostatically filter particles from the fluid stream. The UV light source is positioned to subject the photocatalyst to ultraviolet light and may be arranged upstream, downstream, or intermediate the electrostatic filter. With this arrangement, the ultraviolet light that impinges on the photocatalyst causes a photocatalytic oxidative reaction to occur at the photocatalyst that is capable of reducing volatile organic compounds carried in the fluid stream. In other (separate) aspects, the reactor includes an absorber or an oxidation catalyst.Type: ApplicationFiled: July 30, 2007Publication date: July 17, 2008Applicant: AIRINSPACE B.V.Inventors: Vance BERGERON, Laurent Adrien FULLANA
